Dolphins and Whales Have Sophisticated Human-Like Societies
The brains of cetaceans and primates share features that are rarely found elsewhere in nature.

No one has ever been able to fully measure the intelligence of whales, dolphins, and porpoises, but evidence continues to mount that it is impressive. Consider Kelly, a dolphin formerly housed at the Institute for Marine Mammal Studies in Mississippi. She was trained to keep her outdoor tank clean. If she brought a piece of litter to her trainer, she was awarded with a fish.
The enterprising Kelly figured out that if she wedged a single piece of litter under a stone and ripped it into multiple pieces, she would receive more fish. She then determined that she could increase the amount of "litter" in the tank by using the earned fish as bait to catch unwary birds. She subsequently taught these clever strategies to her calf.
